Arnold Tharrington works in the Scientific Computing Group of the National Center of Computational Sciences at Oak Ridge National Laboratory (ORNL). He has been with Scientific Computing at ORNL since 2005 when ORNL’s Jaguar, the first open Science petaflop supercomputer, was just a few teraflops.

His primary job is to help OLCF users advance their scientific research on OLCF’s Titan supercomputer. Other responsibilities include helping with the acceptance of OLCF’s supercomputers (Jaguar, Titan, Summit, etc.).

His research interests broadly subsist under software development of scientific algorithms for HPC architectures. In particularly, he specializes in Molecular Dynamic algorithms for hybrid CPU/GPU architectures.
